Those are at least 4 questions in one, let's see what we can do about it :-)

First, there is no need to create another Excel instance, just add your code into an empty workbook (or into your master document, if that's ok for you)

 Public Function OpenWorkbook(mypath As String) As Workbook
     Workbooks.Open Filename:=mypath
     Set OpenWorkbook = ActiveWorkbook
 End Function

Usage:

 Dim wb as workbook, ws as worksheet
 set wb = OpenWorkbook("your path")
 set ws = wb.Sheets(1)

Avoiding the 2nd Excel instance automatically solves your problem with any VBA macros in your survey documents - when you open another workbook from within a running macro like the way above, the user won't get any security warning. (By the way, do the survey documents have to contain any macros?)

Copying data from that sheet into your workbook goes like this:

 ThisWorkbook.Sheets("Name of your sheet").Range("A1") = ws.Range("A1")

Iterating through a bunch of Excel files in a folder is described, for example, here

Hope that helps.
